Energy in SHM: Practice Problem & Solution

In case of a forced vibration, the resonance wave becomes very sharp when the: (2003)
Damping force is small
Restoring force is small
Applied periodic force is small
Quality factor is small

Solution Explained:

To solve this problem, we apply the core principles of Energy in SHM. Understanding the underlying formula is key to arriving at the correct answer below:

The sharpness of resonance in a forced oscillator is inversely proportional to the damping present in the system. Therefore, the resonance wave becomes very sharp when the damping force is small.
